Alloy Steel Sheets
Stellanox Steel is a leading supplier of premium Alloy Steel Sheets, known for their high strength, excellent formability, and resistance to fatigue and wear. Our alloy steel sheets are widely used in critical industrial sectors such as automotive, aerospace, oil & gas, defense, and heavy machinery—offering exceptional mechanical performance under high-stress, high-temperature, and impact-heavy conditions.
Designed for fabrication, structural use, and thermal environments, our alloy sheets deliver durability and dimensional accuracy for your most demanding applications.
What are Alloy Steel Sheets?
Alloy Steel Sheets are flat-rolled steel products made by alloying carbon steel with elements like chromium, nickel, molybdenum, manganese, and vanadium to enhance mechanical strength, hardness, and corrosion resistance.
Compared to standard carbon steel sheets, alloy steel sheets offer superior tensile strength, improved heat resistance, and excellent wear performance. These qualities make them ideal for manufacturing components that require durability, resistance to fatigue, and exposure to high pressures or temperatures.
